cpuidle_coup...state_verify(9)

💅 NAME 💅

okay bestie, welcome to the Kernel API Manual page for cpuidle_coup...state_verify(9) — she's here to check those coupled states ✨.

cpuidle_coupled_state_verify — check if the coupled states are correctly set. no cap, that's the whole name 🫶.

---

🌸 SYNOPSIS 🌸

the exact signature, character for character:

int cpuidle_coupled_state_verify (struct cpuidle_driver *drv );

---

🎀 ARGUMENTS 🎀

• drv — struct cpuidle_driver for the platform.

---

🦋 DESCRIPTION 🦋

okay so, this function returns 0 for valid state values, and a negative error code otherwise:

• -EINVAL — if any coupled state(safe_state_index) is wrongly set.

that's the listed error moment, bestie 💀✨.
